Description

Deletes an existing record in a table in one line.
You pass to this function table name (and optional filename).
To identify the record you pass the name of the ID field and the value for the record. The ID field must be unique.

Please note that FM.DeleteRecord and FM.DeleteRecords are nearly identical. Just FM.DeleteRecord provides the check to make sure only one record matches while FM.DeleteRecords allows several records to be deleted. So with FM.DeleteRecords you can easily erase a lot of data if you pass wrong ID!

With plugin version 7.2 or later, you can specify fields and table via IDs and the plugin will lookup them for you at runtime.

Version 8.2 allows to specify up to 3 ID parameters.

With plugin version 8.4 or newer, you can use GetFieldName() function to query field names and the plugin removes the table prefix with :: in the field name before passing it to SQL engine.

You can use FM.ExecuteSQL.LastSQL function to see later what SQL was created and run.

Examples

Delete a record based on values:

Set Variable [ $r ; Value: MBS( "FM.DeleteRecord"; Get(FileName); "Contacts"; "First"; "Christian"; "Last"; "Schmitz"; "Company"; "Test Inc.") ]
